Probably has something to do with all the stuff in the agreement no one ever reads. Maybe each of those is different, and they're trying to see how many silly things people will accept before they give up.

At least we macrumors readers know where to look when we observe these kinds of problems. I feel bad for the first-time iPhone owners who just bought a new iPhone 5 and are trying to get their first third-party app and wondering why it doesn't "just work".

It would be nice if Apple did something about the endless loop when this kind of thing occurs; instead of telling me to try my purchase after I hit "Agree", tell me something is wrong and to try again in a few hours.

It serves them right. A pointless novella of unreadable legalese prose, constantly updated and constantly requiring you to "agree" (but not actually read the stupid thing) if you want to just sync your phone or ipod.
